Abstract: The present invention pertains to a process for preparing a powder coating composition, the process comprising the steps of: a. providing a set of base compositions, each base composition comprising a liquid carrier and one or more constituents responsible for an intended property of the coating product, at least one base composition A being an aqueous dispersion or emulsion of a film-forming material, b. selecting base compositions to be used to obtain the intended end product property, said base compositions comprising at least one base composition A as specified; c. mixing the selected base compositions in a ratio suitable to obtain the intended end product property; d. drying, preferably spray-drying, the mixture of base compositions or otherwise removing the liquid carrier(s), and e. simultaneously or subsequently, combining the particles of the base compositions into larger particles. Preferably, the particles of film-forming material in base composition A have a d(v,50)<5 ?m.

Abstract: A process for preparing an aqueous powder coating dispersion comprising components A and B, wherein component A is a binder resin or a mixture of binder resins and component B is a crosslinker or a mixture of crosslinkers or component A is a crosslinker or a mixture of crosslinkers and component B is a binder resin or a mixture of binder resins, wherein the process comprises the steps of: a) dispersing a composition comprising component A by the addition of an aqueous medium in a phase inversion emulsification process, b) adding component B simultaneously with or after the addition of the aqueous medium, and c) optionally mixing the obtained composition to obtain a dispersion comprising components A and B. The process enables the preparation of stable powder coating slurries with particles in the range from 50 to 800 nm.

Abstract: The present invention relates to a process for the preparation of a foamed article having a foam density of less than 180 kg/m3 and an average cell diameter of less than 1.5 mm comprising the extrusion of a molten semi-crystalline thermoplastic resin composition in the presence of a foaming agent, with the semi-crystalline thermoplastic resin composition comprising a polymeric epoxide containing at least two epoxide groups being a copolymer of a monomer mixture comprising at least one C10 to C18-olefin and at least one ethylenically unsaturated compound comprising an epoxide group. The process results in the preparation of foamed articles having a regular and homogeneous structure. Another advantage of the present invention is that it is not necessary anymore to add a compound of Group Ia, IIa, or IIIa of the Periodic Table, such as LiCl, to the extrusion process.
